Abstract: A pointing device which can be operated by a disabled person with a declined muscular strength, even when the person lies in a bed, to move a cursor and make a click separately not only by one hand but also by a body portion having a motor function with a light touch without any complex movement and large motion, and which does not need any operation area.

Abstract: An information indicating that a pattern machining data for an industrial machine, which data is a collection of sectional machining data each including workpiece feed amount for each sectional machining and machining information for each sectional machining, is made contiguous to another machining data is inserted into a predetermined one of the machining data so that a plurality of machinings whose data size exceeds a capacity of a machining data memory of the machine can be can be performed thereby continuously.

Abstract: A data preparing apparatus includes an input device for inputting coordinate data such as a configuration and pattern to be processed and processing conditions, a memory device for converting the coordinate data inputted by the input device into variable coordinate data varying relatively according to the processing conditions and storing the variable coordinate data as a pattern data for processing, a predicting device for predicting a processing information resulting from a processing performed on the basis of the pattern data stored in the memory device and an output device for outputting the processing information obtained by the predicting device. The processing information includes at least one of a processing time, an area to be processed and a processing path. The predicting device calculates a processing time according to a preset processing rate.
